mred:connections-media-canvas%

Superclass: wx:media-canvas%

The connections classes are designed to provide low level links between classes that may be interested in each other. Most of the across class dependencies in the system have been centralized here in this set of classes.

All of the maintence of these connections is performed here automatically, as long as you use these classes or classes that inherit from them.

• (make-object mred:connections-media-canvas% parent x y width height name style scrolls-per-page buffer) -> mred:connections-media-canvas% object
      parent : wx:frame% object or wx:panel% object
      x = -1 : small integer
      y = -1 : small integer
      width = -1 : small integer
      height = -1 : small integer
      name = "" : string
      style = 0 : small integer
      scrolls-per-page = 100 : small integer
      buffer = null : wx:media-buffer% object or null

  Most of the arguments here are as with wx:canvas%. Only the last three arguments are specific to wx:media-canvas%.

  The style flag is a bitwise combination of

  • wx:const-mcanvas-no-h-scroll -- doesn't allow horizontal scrolling
  • wx:const-mcanvas-no-v-scroll -- does't allow vertical scrolling
  • wx:const-mcanvas-hide-h-scroll -- allows horizontal scrolling with the caret, but doesn't show a horizontal scrollbar
  • wx:const-mcanvas-hide-v-scroll -- allows vertical scrolling with the caret, but doesn't show a vertical scrollbar

  While vertical scrolling of editor buffers is based on lines, horizontal scrolling and pasteboard vertical scrolling is based on a fixed number of steps per horizontal page. The scrollsPerPage argument sets this value.

  If the canvas is initialized with null for buffer, a buffer can be installed with set-media.
